如何将列表元素转换为字符串数组

Question

var categoryList="[Service,Ticket,Bill,Entertainment,Restaurant]";

我想将上面的String转换为String数组，如下所示：-

var categoryList=["Service","Ticket","Bill","Entertainment","Restaurant"];

任何解决方案都是可观的。

Answer 1

categoryList = categoryList.replace(/\[|\]/g,"").split(",");

Answer 2

您可以使用slice()和split()

 var categoryList = "[Service,Ticket,Bill,Entertainment,Restaurant]" .slice(1, -1) // get `[` and `]`removed string .split(','); // split based on comma to get array console.log( categoryList ) 

Answer 3

var yourString = "[Service,Ticket,Bill,Entertainment,Restaurant]"

var categoryList = yourString.substring(1, yourString.length-1).split(",") // removing [] and splitting with `,`

Answer 4

使用String.match函数的另一个简短解决方案：

var categoryList="[Service,Ticket,Bill,Entertainment,Restaurant]";
console.log(categoryList.match(/\w+\b/g));  // ["Service", "Ticket", "Bill", "Entertainment", "Restaurant"]
